f Specification forming part ofv Letters, Batent No. 175,307, datedMarch 28, 1876 application filed January 17, 1876.

To all whom it maygeoneem Be it known that I, LAFAYETTE L. TRE- MAN, ofIthaca, Tompkins county, New York, have invented a new and usefulImprovement or Fixturefor Umbrellas, which improvement I have set forthin the following specication, reference being had to the accompanyingdrawings.,

My invention relates to the construction of the frames of umbrellas, andthe nature ot my invention will be apparent as I describe it.

Figure l is an elevation of my umbrella, showing, in part, the handle orstaff, the stretchers or braces, the spreaders or bows, the

notch or top piece, and the ruimer orhand-,

slide, which have my improved hinge aflixed to them. Fig. 2 is a sideelevation of my top piece, showing the manner of making the holes forthe circular hooks of the bows and braces. Fig. 3 is designed to showamodilication of my top piece, and Fig. 4 shows the runner Without thebraces.

In Fig. 1, a is the handle or staff, `and b is the top notch, and c care two of the spreaders or bows, bent to a semicircular hook at theirtop c', where they pass through apertures in the projection, partition,or septum c,- aiid d is the runner or hand-slide, with a likearrangement about the septum on its top d', through which the hook ofthe brace or stretcher e passes. At f is a curved piece of metal, joinedby solder to the light steel spreader or bow c, to which the brace isfastened by a pivot.

My peculiar hinge will be particularly described. The apertures c, Fig.2, are seen to be circular and cut away in part to their middle, and aremade preferably as follows A blank is cast, or otherwise made, and holes0 are drilled equally apart in the circumferenceof the blank, through tothe hollow just within the septum. (See Fig. 1.) Next, the base ot' theblank is cut, preferably, (see Fig. 4,) so as to leave the septum d' ofthat figure and the tube d", care beiiighad to cut to the center of theholes c' of the various figures. This leaves the top piece or ruimer asseen in the figures. And it is apparent that, when the umbrella isexpanded, the straight part of the bows and ot' the braces, next to thecurve of the hooks of the tops of `the boivsiandl bottom, ofntheflbraceslie. in the cavity thus left of that part of the holes outside ot' theseptuins c" and d', and that thus the bows or spreaders and the bracesor stretchers are stifiiy held when the umbrella is expanded.

The object of that part of the runner called the tube d is to afford thehooks a bearing on this tubular part and not on the handle, for thepurpose of preventing the defacing of the handle by these ends of thehooks, and to afford a rmer joint when the same tubular part is made tothe top piece b.

Numerous equivalents to my device suggest themselves. It will be seenthat, in Figs. 1 and 2, the septum o" is a ring suspended from the pieceb, above which is anothei1 riiig-also part of the piece b-which has thebracing c, which I have described. And the bracing may be made bycutting slots through the ring, above the septum, of a width equal tothe bows or stretchers, in the direction indicated by the arrow in Fig.3. This gives a less support to the bows or stretcliers, yet does notdestroy the stiffening ot' the frame in the manner I have described.And, that l may show how very flexible is the arrangement of theseparts-viz., the septum ring and the `brace-ring, as well as the tubularpart d of Figs 1 and 4 1 have, in Fig. 3, changed considerably thesituation and proportions of these various parts. The tube d is iiiadelonger and thicker than in Fig. 1, and, by a pin through it, holds thetop piece to the sta' a, and the holes c are drilled as shown by thearrow h, but the septum is not cut out by turning, but has simpledrill-holes made, as seen by the arrow i, and in section at and tocomplete the change a saw-cut is made, as indicated by the arrow j, andseen in section atj. Yet it is evident that .these changes leave thecomponent parts of my inventionviz: the septum ring-adapted to hold astretcher or bow, with a seiiiicircular hook on its end iii it, and witha bracing against a part of the top piece on the sides ot' the straightpart of the bow or stretcher, just outside of the hook. So of othermodifications l might describe.

It is not necessary to describe methods ot' stamping, spinning, or bydies making my improved top picco and ruimer. or the joints ot' these,either wholly or in part, as these methods are well understood. Be theprocess of construction what it may, itis the special construction andcombination ot'liooked bows or spreaders and stretchers, and theapertures through the septum or projection, as shown, which apertures,arches, spaces, or similar portions act as bracing spaces or inortises,that constitutes my invention. The further uses and advantages ot' myinvention are apparent to those skilled in the art to which itappertains.

I claim- 1. The rings, septums, or projecting circles c and d', made aspart of the top piece and slide piece, parallel to the handle of the um-
